It's not something I want to be good at.

When we bought our own house, the crawlspace had issues and they did a really great job encapsulating it with very little space to work with.

Our house was built with some pipes in the crawlspace that were on the outside wall and they came back to add extra insulation for us. I highly recommend this company!

Recently a company connected with Dominion contacted my husband and me to offer a home energy…read morereview and estimate on weatherizing our house in time to take advantage of the tax credits available until the end of the year. Since we did not know enough to evaluate the proposal he provided after his review, we talked with someone we knew who was volunteering with a climate advocacy group in this area. He suggested we contact Mohammed at Home Energy Solutions for an energy audit. We did so and were able to schedule it very quickly with Mohammed spending a great deal of time doing a thorough inspection of our three attics and our many windows and doors. We were surprised at just how bad the situation was in general air leakage, in the ductwork, and in the insulation over one part of our house where, from the pictures Mohammed took, it looked like a raccoon had gotten into the attic and torn up the insulation. When Mohammed sent us a contract to fully insulate our three attics, removing the insulation in parts, sealing the edges and around lights, and more, and we had a ton of questions, he promptly responded with clarifying information and willingness to adjust the work and add on caulking our windows and weatherstripping a door and more. Also, the price was most reasonable -- significantly less than the other company with more items included. He then scheduled the work at our convenience and his team of three, led by Eric, arrived promptly at 8 AM and worked hard until 5:30 pm. In the 53 years we have been in the house we have done about five major remodeling jobs/additions, and a whole bunch more of minor improvements. We have been very happy with most of the firms and workers, and a couple less so. Of all the crews that have worked in our home, Eric and his team were outstanding in every way -- so helpful, courteous, hardworking, quiet, neat, patient in answering questions, and so much more!!! They cleaned up afterwards and it was great to wake up this morning and feel the notable difference in the especially leaky part of the house. We cannot say enough good things about HESS -- Mohammed, Eric and the other technicians!!! And, we are looking forward to significantly lower energy costs. If you want a great job, at a reasonable price, HESS is the place to go!

We love that it came with a pearl certification too so we can have documentation in case we ever want to sell. Just an unbelievable value and we can't believe we didn't do it sooner. Thank you so much HESS! Such a great experience! Wanted to see the best way we could improve the comfort level of our three story townhome and now we know how to do that and so much more.
